SQL Server 2016 - FÜR JSON PATH entspricht FOR JSON AUTO

Question

Verwenden von SQL Server 2016 (Azure) Ich möchte die sekundären t2 Daten als ein Array, um die primäre Datenwiederholung zu vermeiden. Etwas wie folgt aus:

Aber ich kann es nur tun mit FOR JSON AUTO und kann die Eigenschaftsnamen nicht kontrollieren ...

Wie kann ich tun dies mit FOR JSON PATH oder dergleichen, so kann ich Kontrolle über Eigenschaftsnamen?

SQL für den Test:

create table #t1 (id bigint, name varchar(20)) 
create table #t2 (id bigint, idBase bigint, name varchar(20)) 

insert into #t1 values (1,'teste1') 
insert into #t1 values (2,'teste2') 
insert into #t2 values (1,1,'teste11') 
insert into #t2 values (2,1,'teste21') 
insert into #t2 values (3,2,'teste32') 

select 
    t1.id as 'base.id' 
    ,t1.name as 'base.name' 
    ,t2.id as 'base.secondary.id' 
    ,t2.name as 'base.secondary.name' 
from 
    #t1 as t1 
inner join 
    #t2 as t2 on t1.id = t2.idBase 
for json auto 

Dank!

verwenden "für json auto":

select t1.id as [base.id], 
     t1.name as [base.name], 
     (
      select t2.id as [base.secondary.id], 
        t2.name as [base.secondary.name] 
      from #t2 as t2 
      where t2.idBase = t1.id 
      for json auto 
     ) as [t2] 
    from #t1 as t1 
    for json auto 

Ergebnis:

[{ 
    "base.id": 1, 
    "base.name": "teste1", 
    "t2": [{ 
     "base.secondary.id": 1, 
     "base.secondary.name": "teste11" 
    }, 
    { 
     "base.secondary.id": 2, 
     "base.secondary.name": "teste21" 
    }] 
}, 
{ 
    "base.id": 2, 
    "base.name": "teste2", 
    "t2": [{ 
     "base.secondary.id": 3, 
     "base.secondary.name": "teste32" 
    }] 
}] 

verwenden "für json Pfad":

select t1.id as [base.id], 
     t1.name as [base.name], 
     (
      select t2.id as [id], 
        t2.name as [name] 
      from #t2 as t2 
      where t2.idBase = t1.id 
      for json path 
     ) as [secondary] 
    from #t1 as t1 
    for json path 

Ergebnis:

[{ 
    "base": { 
     "id": 1, 
     "name": "teste1" 
    }, 
    "secondary": [{ 
     "id": 1, 
     "name": "teste11" 
    }, 
    { 
     "id": 2, 
     "name": "teste21" 
    }] 
}, 
{ 
    "base": { 
     "id": 2, 
     "name": "teste2" 
    }, 
    "secondary": [{ 
     "id": 3, 
     "name": "teste32" 
    }] 
}]
